鎖を解除するものである。 However, for some applications, it is desirable to directly sense the temperature of the water within the radiator rather than the temperature of the air passing through the radiator. For example, the one disclosed in Japanese Patent Publication No. 18325-1973 has been proposed. A storage chamber and an operating chamber are formed in the fluid chamber in the fluid housing by a partition plate, and the partition plate is provided with a communication hole that communicates the two chambers, and a valve plate is provided to open and close this communication hole. When the water temperature in the radiator rises, an electromagnetic coil is activated to move a sensitive operating rod attached to the valve plate, thereby releasing the valve plate from closing the communication hole.

It is not assembled and is placed in front of the vehicle, which has the disadvantage that not only does it require extra space to install it in the vehicle, but it is also expensive as a whole. One is that the rotation axis is a hollow body,
The electromagnetic coil must be placed in the hollow part, and the sensitive operating rod must also be placed in the hollow part.
The structure of this part is significantly different from that of the air temperature sensing type, and has the disadvantage that the structure is complicated and expensive.

The structure is extremely simple and provides an inexpensive viscous fluid coupling.

ある。Effects of the invention This invention is as described above, and an electric coil is placed close to the outer circumference of a solid rotating shaft to selectively magnetize this rotating shaft. An electric coil and an armature are simply attached to a conventional air temperature sensing type viscous fluid joint, and when the rotating shaft becomes magnetized, the armature is moved and the valve arm is used to block the flow of fluid between the storage chamber and the working chamber. Therefore, it is not necessary to replace the main parts of conventional fluid couplings of this type, and it is possible to easily convert them to electromagnetic fluid couplings without major design changes. Although the manufacturing technology of the conventional air temperature sensing type viscous fluid joint can be used to a large extent, it can be used as a water temperature sensing type fluid joint in a radiator, which is different from this. In addition to having a simple structure, it is also easy to manufacture and can be provided at low cost.
